Article Synopsis
- Chitin nanocrystals (ChiNC) were created using a treatment with p-toluenesulfonic acid and choline chloride deep eutectic solvent, resulting in crystals that vary in size (12-44 nm wide, 206-399 nm long) while preserving their crystalline structure and functional groups.
- The immobilization of porcine pancreas lipase (PPL) onto ChiNC resulted in PPL@ChiNC, which displayed enzyme loading of 35.6 mg/g and an impressive activity recovery of 82.5%.
- The properties of PPL@ChiNC, including thermal stability and adaptability to changes in pH and temperature, were enhanced compared to free PPL, suggesting potential applications in biocatal
Crystallization and preliminary X-ray crystallographic analysis of α-glucosidase HaG from Halomonas sp. strain H11.
Acta Crystallogr F Struct Biol Commun
April 2014
The α-glucosidase HaG from the halophilic bacterium Halomonas sp. strain H11 catalyzes the hydrolysis of the glucosidic linkage at the nonreducing end of α-glucosides, such as maltose and sucrose, to release α-glucose. Based on its amino-acid sequence, this enzyme is classified as a member of glycoside hydrolase family 13.

Azo dyes are major synthetic dyestuffs with one or more azo bonds and are widely used for various industrial purposes. The biodegradation of residual azo dyes via azoreductase-catalyzed cleavage is very efficient as the initial step of wastewater treatment. The structures of the complexes of azoreductases with various substrates are therefore indispensable to understand their substrate specificity and catalytic mechanism.
